This study aims to obtain psychological aspect of children for understanding memories of disaster prevention education materials. For this purpose attitude surveys were conducted. First, a video-story was created from past landslide disaster at Mukawa of Yamanashi Prefecture in 1959. The story contains a lesson about the disaster. From the video-story, the memories of children were analyzed by dividing the video-story into illustrations and narrations. The main finding of analysis shows that a possibility that the illustrations and the narrations of the scenes chosen by children had emotional stimuli (emotional arousal) which made the children's preserve their memories.

Fukui Heavy Rainfall on July 18, 2004 gave the great damage to the Fukui City area as well as the mountainous midstream area of the Asuwa River. The major damage in the Fukui urban area is the destruction of the embankment at the left bank of the Asuwa River. Flood water depth and flood level were measured at 146 spots, and overflow depth above the embankment of the Asuwa River was also at 10 points. In addition, flood deposits were sampled and analyzed the grain size at 32 points. The inundation water flowed into the urban area from the collapsed embankment had one main flow along the main prefectural road which extends from east to west, and pooled in the lower area of the dammed-up tributary floor.

Waves in the Western Pacific Ocean and at selected points along the Pacific coast of Japan are hindcasted for 118 typhoons from 1940 to 1991 by use of two kinds of spectral wave prediction models. The maximum wave height at each point is estimated during a typhoon. These new maximum wave height data are added to those in the concerned area for 125 typhoons from 1934 to 1983 obtained by Yamaguchi et al. to make a longer data set of maximum wave heights caused by a total of 243 typhoons from 1934 to 1991. Spatial distribution in the Western Pacific Ocean of the most extreme wave height and wave height for return period of 1OO years, and their variations along the Pacific coast of Japan, are re-estimated on the basis of statistical analysis of the data and compared with the results of Yamaguchi et al. By adding the new data, the main conclusions obtained by Yamaguchi et al. are still valid except for the data in the Western Kyushu coast.

The Typhoon 0108 (Typhoon Toraji) attacked the eastern and central Taiwan on 30 July, 2001. This typhoon brought about the heavy rainfall distributions. In the central area of Hualien-ken and the southern area of Nanto-ken, the hourly rainfall more than 100 mm lasted 3 hours, and the total rainfall amounted to more than 400 mm. As the results, the heavy debris flows occurred in many places in both Hualien-ken and Nanto-ken, and the severe inundation flow occurred due to both overtopping flow and bank breach in Nanto-ken. By these flood and sediment disasters, more than 210 persons were killed or missing and huge damages spread out all over the country. This report summarizes the findings of these disasters obtained through the field survey.

The objectives of this paper is to show how to estimate loss of human lives due to catastrophic earthquake disaster. The accuracy of damage estimation decides efficiency of search and rescue activity just after earthquakes in post-disaster crisis management. This is also very important to have good preparedness in pre-disaster risk management. The number of loss of human lives due to collapsed wood houses is major source of victims in our country. The data of the Great Hanshin-Awaji earthquake disaster contribute to make the damage estimation accurate. Quantitative prediction about human damage is also proposed here with new relationships in accompany with railway accidents, highway accidents and coming tsunami. Moreover, macroscopic analysis of death toll is presented from the view point of data analysis on catastrophic natural disaster.

By a stochastic model, the future course and central pressure of a typhoon are simulated as a function of the motion and the change in central pressure depth. Δp, for the past six hours. The gradient wind is computed as a wind balancing to the simulated pressure pattern, and then the sea-surface wind is estimated. As a case study, occurrence probabilities of severe wind for Typhoon 9019 (FLO) are predicted for the period when it was approaching to the Japanese Main Islands. At the coast line of the Kii Peninsula, occurrence probability is 25% on three days before landfall, but it increases to 60% on two days before landfall. This model can be used in estimation of tidal waves and a design wind for huge buildings and structures, and it can be also applied to an economical planning in disaster prevention works.

Disaster education is one of the most important components for building a resilient society. School disaster education especially has an effect on spreading awareness and knowledge of disasters widely. In the past decade, the world has faced many natural and human made disasters. People's awareness of disaster impacts is becoming one of the driving forces for disaster education. However, disaster education should not be based only on disaster impacts. This is because the earth repeats a cycle of active and inactive periods. Hence, consensus between students, teachers and parents is necessary to realize sustainable disaster education in schools regardless of the occurrence of disasters. A questionnaire survey for junior and senior high school students in Wakayama prefecture, Japan was conducted on the first and second of November, 2006. The purpose of this survey was to inquire into students' attitude toward disaster learning in schools in the context of the educational curriculum. In order to keep reliability of this paper, 204 answers from junior high school students in Hirogawa town were selected for this paper from all answers. The result of analysing statistical data revealed several facts. Firstly, all of students have experiences of disaster education in schools and these are thought of as useful for their future life. Secondly, more than 90% of students learn about disasters in the integrated study time slots. Finally, through the comparison between the students who evaluate previous disaster education positively and the students who do not evaluate previous disaster education positively, the former students evaluate future disaster education in schools more positively than the latter students. Improving disaster education based on the people's attitude is one of the most important factors needed to build sustainable school disaster education in Japan.

The second largest flood in 2002 occurred in the Chao Phraya River basin, Kingdom of Thailand. The field survey was carried out in the middle and lower part of the Chao Phraya River basin two weeks after the peak of the flood terminated. The result indicated that middle basin, especially Ang Thong, Ayutthaya and Sing Buri cities had suffered a heavy damage. In the meantime, there was little serious damage from the inundation by river water in Bangkok city that is located in the lower basin area. The following two factors are mentioned as the reason; (1) In Bangkok, the flood discharge had been reduced by the time it reached the lower basin area because of the overtopping in the middle basin. (2) The flood discharge has been degreasing in the downstream of the Chao Phraya River basin year by year since the Bhumibol and the Sirikit dams were constructed in the upper basin. In addition, the evaluation of the provability was carried out on the flood in 2002 using the generalization extreme value distribution. The flood was estimated under the 10-year return period discharge and it turned out the flood with the high possibility of occurrence.

A heavy rainfall caused by typhoon No. 0514 (Nabi, GLIDE: TC-2005-000154-JPN) and a stationary front occurred in Japan from September 4 to 8, 2005. A 1238-mm, 48-hour precipitation was recorded at Mikado in Miyazaki prefecture. This was the highest recorded precipitation of all observatories administered by the Japan Meteorological Agency since 1979. Based on data from the agency, the highest 24-hour precipitation records in the last 25 years were revised at 56 observatories, and the highest 48-hour precipitation records were revised at 64 observatories as a result of this rainfall. However, there was no observatory where the highest 1-hour precipitation was revised. In this heavy rainfall, 2,834 houses were destroyed and 21,834 houses were inundated; most of the property destruction was caused by inundation. In total, 29 persons were killed or missing in 8 prefectures: 13 in Miyazaki prefecture, 5 in Kagoshima, 4 in Ohita, 3 in Yamaguchi and 4 in others. Of these deaths, 22 were attributable to sediment disaster. On the other hand, in Hinokage town, Miyazaki prefecture, there were no deaths even though a large number of houses were destroyed. This is because all the residents had taken refuge at least 6 hours before the flood and debris flow occurred. It should be noted that in Miyazaki city, an electronic bulletin board system (BBS) administered by the city office was helpful. Whenever a resident used the BBS to ask a question, the city office replied within several minutes. With this system, information was exchanged efficiently and there were no incidences of online vandalism. This example showed the potential for official disaster BBSs in Japan.

The horizontal wind field of the typhoon, T9119,was analyzed using the surface wind data at the meteorological stations in Japan. In this analysis, observed wind speeds were corrected according to the surface roughness of each station. The 10-min mean maximum wind speed attained to 40-50ms^<-1> over flat surface in western Japan and the coastal area of Sea of Japan. The calculated wind field from the empirical formula compares favorably with the observation, and also suggests that wind speeds around Japan are enhanced by fast moving velocity of the typhoon nearly 100km h^<-1>. The wind storm of T9119 is as strong as those of the strongest typhoons which landed in Japan for recent 40 years. The gust factor in typhoon area slightly increases during recent 40 years, which result is mainly attributed to the increase of the surface roughness z_0 around each meteorological station.

To explore a change of typhoon disasters in the area around Ise Bay and its feature, some investigations are made on the relation between the destructive power of 130-typhoons which attacked the area for seventy five years from 1912 to 1986 and the damages caused by the typhoons in both prefectures of Aichi and Mie. It is revealed that although the typhoons accompanying storm surge are very dangerous for both the prefectures, countermeasures for typhoon disaster prevention which have been provided since 1960 are fairly effective against the attack of such the typhoons and succeed in decreasing the damages. While, it is pointed out that the rate of the damages to the power of the typhoons which attacked both the prefectures after 1960 rather exceeds that before 1959 and typhoon disasters are changing in quality since 1960.

A large earthquake (Mw7.4) occurred on January 22, 2003 off the Pacific coast of the state of Colima, Mexico, which was felt strongly throughout the state and its adjacent regions. The hypocenter was located near the suggested boundary between the Rivera and Cocos plates both subducting beneath the North American plate, and close to the southeastern rim of the source region of the 1995 Colima-Jalisco earthquake (Mw8.O). From a centroid moment tensor (CMT) inversion of teleseismic waveforms, the 2003 earthquake has been shown to have a thrust fault shallowly dipping toward NNE. The ruptured source region estimated from the aftershock area with a radius of about 30 km extended over part of the seismic gap left unbroken between the source areas of the 1973 and 1995 previous large earthquakes, and overlapped the southeastern part of the 1932 and 1995 source regions. The earthquake has been recorded at various seismograph stations not only in Mexico but also worldwide. The maximum ground acceleration recorded at hard sites during this earthquake exceeded 100 gals in the epicentral region, and was 2-3 gals at inland stations 800 km away from the epicenter. The seismic intensity in the cities of Colima and Tecoman was reported to be VIII on the modified Mercali scale. The state of Colima and the adjacent states suffered extensive damage, including 15,000 damaged houses which were mostly unreinforced masonry and brick structures. Landslides and liquefactions were also reported near the epicentral region and along the coast.

The severe disaster caused by gusts and hailfalls occurred in the southern inland of Akita Prefecture on August 6,1985. This report deals with the outline of meteorological conditions, damages and characteristics of the gusts in relation to the hailstorms. The following main results were obtained : l) The gusts accompanied with hailfalls were brought about by well-developed thunderstorms related mainly to the unstable stratification by advection of upper cold air. 2) The damaged area by the gusts is about 5 km in north-south direction and about 4 km in east-west direction. The degree of damages is remarkable in western and southwestern side of the hailfall area. Furthermore, the gusts show a divergent tendency in the direction of mainly west, southwest and south from the damaged area by hailfalls. Therefore, it seems that the damages by gusts was caused by the downburst accompanied by well-developed cumulonimbus. 3) Most of the damages were the injury of heads of rice plants and trellises and blossoms of hops by hailfalls and gusts.
